JAMES W. HANKENSON AND WINSLOW BAKER, OF MINNEAPOLIS, MIN- NESOTA.

Letters Patent No. 108,354, dated October 18, 1.870.

IMPROVEMENT IN COMBINED EAVES-TROUGHS AND LIGHTNING-RODS.

The Schedule referred to ln these Letters Patent and making -part of the lame.

Be it known that we, J AMES W. HANKENsoN and WINSLOW BAKER, both of Minneapolis, in the county of Hennepin and State of Minnesota, have invented .certain new and useful Improvements consisting of a Combined Eave-'lrough and Lightning-Rod, of which the following ,is a specification.

Our invention relates to the construction of eavetroughs, and the conducting-pipes 'connected therewith, of continuous copper strip, having a tin coating upon the inside; to the insulation from the building ofthe same by means of brackets, which are nonconductors of electricity, and to their connection at the eaves of the building with a lightning-rod.

Theadvantages to be secured are- `irst,'the gutter being thus constructed of durable material, without joints, and with .a perfectly smooth surface, no particles of water can remain in it to-occasion corrosion and leakage, as in metallic gutters now m use.

Second, the cave-trough and pipe being of copper, being insulated, and being connected with the lightning-rod, are made to serve the additional purpose of a lightning-conductor. v

lo enable others to make and use our invention, we will describe its construction and operation, reference being had to the accompanying drawing and the letters ot' reference marked thereon, which make a part of this specification.

A is an cave-trough, made of one continuous strip of copper, rolled out the required width and thickness, and having the inner surface tiuned over to prevent the possibility of any injurious eiect from the copper upon the water.

A wire may be rolledv into the edges of the striptrough. to add stiiiness and preserve its shape.A

Bis a water-pipe, ot' the same material as A, Ato which it is jointed, and which runs down the building and into the ground.

(l [l d are insnlating-brackets, for attaching the eavetroug'h and pipe to the building.

C is a copper lightning-conductor, att-achedto the roof by insulators, and jointed to trough A at E.

G is a pipe, of non-conducting material, jointed to B, for the purpose of carrying the water to the cis- `tern, while the electric fluid follows conductor B.

What we claim as our invention, and desire to secure' by Letters Patent, is-

I. The cave-trough A, when constructed of one continuousstrip of copper, with the inside surface coated with tin, or other non-corrosive substance, and connected with water-pipe B, made of same material, substantially as and for the purpose described.

2; The combination, with rod (Il, of the copper cave-trough and pipe A-B, whereby the lat-ter is made to serve the additional purpose of a lightningconductor, substantially as and for the purpose described.

3. The combination, with the electrical conductingpipe B, of non-conducting pipe G, for the purpose ot4 carrying the wat-er from the copper conductor to the cistern, substantially as and for the purpose de- M. P. HAWKINS, S. G. ROBERTS.
